Re: How to detect if a disk is an SSD

[Matthias Petermann]

Hello Stefano,

one option might be to check the kernel log via

% dmesg

I would expect some entries like:

ada4 at ata0 bus 0 scbus4 target 1 lun 0
ada4: <SAMSUNG MZ7LM120HCFD-0E003 GXT3003Q> ACS-2 ATA SATA 3.x device
ada4: Serial Number S2NRNXAGC00170D
ada4: 150.000MB/s transfers (SATA, UDMA6, PIO 8192bytes)
ada4: 114473MB (234441648 512 byte sectors)
ada4: quirks=0x3<4K,NCQ_TRIM_BROKEN>

which includes the model number / name. Feeding this into Google should provide clarity if it is a SSD or not.

Best regards,
Matthias
